# NVIDIA Copyright Header

Add the following NVIDIA copyright header to all Python files and shell scripts. The header should include the current year. Exclude test files (files under `tests/` or test-only scripts).

The header must appear at the top of the file. **Always use the current year** (not a hardcoded year):
